Broadly speaking, summer solstice — the longest day of the year, in the northern hemisphere, at least — is a time to celebrate the arrival of warm weather; the impending harvest; and — for some — the birds and the bees. Perhaps more than any other place on earth, summer solstice is associated with Stonehenge and Druids.

I don’t know if the all people who celebrate summer solstice at Stonehenge today are Druids — they look a lot the hippies I went to college with — but their celebrations look like fun. Generally speaking, they feature a lot of dancing and singing and didgeridoo’ing and jumping around. There’s some standing around, too, waiting for the sun to rise.
